| The aim of the present study was to investigate the effects of lysophospholipids on blood parameters in Holstein calves with a diet containing saturated fatty acids. For this purpose, 48 calves (24 male and 24 female) with an age range of 3 ± 1 days and an average birth weight of 39.9 ± 4 kg were selected in a completely randomized design with 4 treatments and 12 replications for a period of 85 days. The experimental treatments were: 1) Basic diet without additives, 2) Basic diet with 3% saturated fatty acid-rich fat, 3) Basic diet with 2 gr of lysophospholipid daily, and 4) Basic diet with 2 gr of lysophospholipid daily + 3% saturated fatty acid-rich fat. Lysophospholipids were added to the milk from days 6 to 64 and to the starter from days 65 to 85. The experimental treatments had no effect on the metabolizable energy (ME) intake of the calves, nor did they significantly influence the final body weight. However, the ME/gain ratio was significantly affected by the treatments (P<0.05), with the groups receiving 3% fat showing the lowest ratio compared to the other experimental groups. Blood parameters, including glucose, cholesterol, triglycerides, blood urea, albumin, total protein, and beta-hydroxybutyrate, showed no significant alterations at the 5, 45, and 85-day. Furthermore, the concentrations of glutathione peroxidase, total antioxidant capacity, and malondialdehyde were unaffected by the dietary treatments. Although fecal consistency was not impacted during the first 1 to 5 days, from 6 to 65 days, and 66 to 85 days, significant differences were found over the entire rearing period, with calves receiving lysophospholipid demonstrating better fecal consistency compared to the control group. In conclusion, the treatments did not affect energy intake, final body weight, or blood parameters; however, the addition of lysophospholipid enhanced fecal consistency, and the 3% fat diet exhibited the lowest metabolic energy to gain ratio. | ||
